I have a saito .91 and am new to using 4strokes. I am running a 14x6 prop and the rpm is about 6180, is this about right. It seems kinda low to me? Also i am having problems getting it to have a smooth transition from idle to max, any pointers on this. I am running this engine on a test stand, in the upright postion and it is spitting an awful lot of fuel out of the carb, is this normal? I bought this motor used off ebay, guy said it ran fine. It is still under warranty as he only bought it in october of last year.

Thanks for any and all help

Keith
